BOSTON, MA--(Marketwire - September 11, 2008) - BioDefense Corporation (http://www.biodf.com) is
in final negotiations with several "key" lead manufacturing companies to
fabricate and assemble components for its highly sophisticated mail
decontamination system, the Mail Defender (V.3).

Recent developments include BioDefense executives traveling to
Shepherdsville, Kentucky in early August to visit with local businessman
Randall Waldman, CEO of Integrity Manufacturing. Integrity, who recently
announced a partnership with California-based electric-car company ZAP
(OTCBB: ZAAP), and who is already a DOD manufacturer, sees the possible new
relationship as a natural fit for Integrity's overall long term strategic
growth plan. Other sites visited in August by BioDefense include candidates
in Maryland, Massachusetts, New York, and Connecticut.

BioDefense Chairman and CEO Michael Lu stated, "Our choice of companies
seeking a partnership is currently narrowed down to a specific list of
manufacturers that includes Integrity. For the right company, this could
translate into several hundred million dollars for the manufacturing of the
Mail Defender V.3 units over the next few years."

Lu added, "Although there is a pool of transportation and engineering
efficiencies to draw from locally, interstate manufacturing relationships
in close proximity to key strategic government locations throughout the
nation are a must."

Jonathan Morrone stated, "The Company has identified several locations
throughout the country for rapid deployment and force protection, and
Integrity Manufacturing happens to be located near one of those locations."

Although no agreement has been signed with Integrity Manufacturing yet,
company officials feel very optimistic about their recent visits. An
announcement will be made at the annual shareholder meeting.
